Vedclass · Answer

(A) In earthworms,nephridia are classified based on their location:$1$. Septal nephridia $(P)$ are present on both sides of the intersegmental septa of segment $15$ to the last,which open into the intestine $(P-I)$.$2$. Integumentary nephridia $(Q)$ are attached to the lining of the body wall of segment $3$ to the last,which open on the body surface $(Q-III)$.$3$. Pharyngeal nephridia $(R)$ are present as three paired tufts in the $4^{th}, 5^{th}$ and $6^{th}$ segments $(R-II)$.Therefore,the correct matching is $P-I, Q-III, R-II$.

Column-$I$	Column-$II$
$P$. Septal nephridia	$I$. $15^{th}$ segment to the last segment
$Q$. Integumentary nephridia	$II$. $4^{th}, 5^{th}$ and $6^{th}$ segments
$R$. Pharyngeal nephridia	$III$. $3^{rd}$ segment to the last segment
